Since their discovery a century ago, the Dunhuang manuscripts have revolutionized the study of Asian religions. Until recently, however, the rich materials relating to esoteric tantric Buddhism have been largely ignored. This volume provides an indispensable doorway into these materials. An introduction summarizes the discovery, worldwide dissemination and general character of these Tibetan treasures. The catalogue entries provide introductory discussions of the manuscripts' contents, in addition to reordering the often scrambled folios, linking them to their long-lost counterparts in other collections, and matching them with corresponding texts in the Tibetan canon. The catalogue includes indices to Tibetan and Sanskrit titles, names and terms, as well as all Pelliot manuscripts referenced. The result is an invaluable resource for scholars of Buddhism.
